Subject Re: Suggestions for upgrading cassandra

I'd review the CHANGES.txt to see what has changed and the NEWS.txt to see
what you need to do before upgrading (config changes, data storage changes,


- Determine what version you are upgrading to, and why
- Snapshot the data across all nodes
- Upgrade the nodes one at a time (rolling upgrade)

For a change this major, you should set up a test cluster and see if there
are any changes after the upgrade.
